Tips:

1. Default bios settings will work.
2. You can choose SMCAMDProcessor.kext instead of SMCProcessorAMD.kext, but SMCProcessorAMD is more stable and simple.
3. Chrome fix by GLfriend running open /Applications/Chrome.app --args --disable-gpu, and in chrome://flags, disable #enable-gpu-rasterization and choose opengl #use-angle flags. And chrome seems usable.
4. Use GLFriend app to open chrome like apps is another option.
5. Virtualization you can use Parallels 13.1, need SYSTEM_VERSION_COMPAT=1 environment variable. You can use this launcher. OR replace Paralles Contents/MacOS/inittool with Tools/paralles.
6. Adobe software like Photoshop has intel_fast_memset issue, you can fix it by running adobe_patch. Older versions of Adobe software (e. g. up to 22.3.1 for Photoshop) need it's legacy version. For details about Adobe patching check thead on macos86.it.
7. Some applications for macOS use MKL - Math Kernel Library. Unfortunately, it does not work on AMD CPUs natively - we need to patch it with this script.
8. Fix sleep follow opencore guide Mainly run:

sudo pmset autopoweroff 0
sudo pmset powernap 0
sudo pmset standby 0
sudo pmset proximitywake 0
sudo pmset tcpkeepalive 0
